    Hi all

    i need to get a pump for a 2.2kw spindle, can anyone recommend a good unit, the 'bay is a minefield of small pumps most of which would likely be crap ;)


    Thanks

    If your coolant is distilled water with a little something to stop it turning funky you could use a pond pump, decent ones are reasonably priced and they will run constantly for years, your setup could then be based around a 4 gallon header tank with a submersible pump with the option to add cooling on the return side,

    If you will not be swayed by logic or experience simply pick the idea you
    like best, but ask yourself why you sought advice in the first place and,
    for a simple life, perhaps consider not doing so in future

    I used a 50/50 mix of water and anti-freeze on the mini-mill.

    The label has disappeared so i have no idea what flow rate to look for, head needs to be 2m max but is small bore tubing - 8mm i think

    I think the min pump had to be 400l per hour. There is quite some loss from that due to height , long lines, lines width, ... In reality the actual flow needed to cool a spindle is minimalistic
